After all the parts were assembled, everyone was looking forward to what they wanted appearing in that small space. Ning Ye was also very much looking forward to it. If successful, this technology would be very important in a certain sense.

Amidst everyone's expectant gaze, the water that had been sprinkled inside quickly began to condense. Although the process was slow, it meant that the device truly had a cooling function.

Zhang Zifeng looked at Ning Ye in disbelief, and Ning Ye nodded firmly, "Congratulations, little guy, you succeeded!"

The cheers were deafening, almost lifting the roof off the building. Everyone reached out to touch it, and sure enough, the icy touch was unmistakable. After a while, they felt their hands begin to ache.

Xia Qingyu still didn't quite understand how this was done. Although he had retrieved all the items and attended the classes, the difference in what they had learned was still too great.

So sometimes these things really seem almost mystical.

Zhang Zifeng said excitedly, "I remember my brother said that ice is a very valuable thing. Does that mean we'll be rich in the future?"

Ning Ye smiled and said, "It's not wrong to think of it that way, but this thing isn't just useful for making ice; it's also very important for other things."

The reason why people invented refrigerators is not just for a taste of cold, but to preserve food.

These items require very strict storage conditions; if the temperature is too high, they may not be able to be preserved. The invention of the refrigerator has solved this problem.

As the ancients said, you reap what you sow. The things you've invested in from the very beginning are finally starting to bring you new returns.

However, this is just the beginning. As for what else they want, we'll have to wait and see. After all, Ning Ye didn't create this special class for money.

The chubby boy said, "Since we can make this refrigerator, does that mean we can actually make everything the teacher mentioned? It's just that we haven't mastered the methods yet. Once we do, everything will appear before our eyes."

Upon hearing this, Zhang Zifeng immediately became even more excited, "Yes, that's right, there's a lot more in the book."

Ning Ye also encouraged them, saying, "The step you have taken today is crucial because it will be of great help to you in the future, and every success you achieve will bring you satisfaction."

Xia Qingyu directly extended her hand to Ning Ye, "I wasn't much of a help this time, but shouldn't you give me a reward? I've been running around doing all this for so long."

Ning Ye flicked Xia Qingyu's head and said, "You're obsessed with money. All you ever talk about is money."

Xia Qingyu rubbed her head angrily, "Hey, if you don't want to give it to me, just give it to me! Do you know how much it hurts?"

"Alright, the principle remains the same: what we did today cannot be easily told to others. Also, the refrigerator we made is indeed useful, but you cannot show it to others."

Zhang Zifeng asked timidly, "Brother Ning, if we don't show these things to others, what's the point of making them? Are we just going to leave them here?"

"Don't worry, of course it's not going to be left here directly. I have other uses for it. You may have to do more, and I hope that each one will be useful in the end."

Just then, Mo Li said, "Young Master Ning, could we consider what we've done as our tuition?"

Ning Ye said with some surprise, "Everything you have here is free, and you're only here because of my request. Why would you say that?"

"I just feel that some things should be calculated a little more clearly. If everything is unclear, it's actually not good."

Ning Ye nodded thoughtfully, "How about this, from now on, as long as anything you make is useful, I will buy it at a price. That way, you won't be left with nothing, and I can exploit you little guys with a clear conscience."

Xia Qingyu immediately protested, "You can't do this! They're all children. How can you bear to bully a group of kids?"

"I'm really sorry, the protest is invalid. Well, I have other things to do, and you all need to continue your studies today. I'll be going now."

After leaving the special class, Ning Ye felt quite satisfied, after all, the seed he had planted seemed to have begun to grow strong.

After the autumn harvest, Ning Ye was preparing to take a long trip. After all, the uprising was almost over, but he had to go to the Xiguan area to do Hu Laosan a big favor. Only after this matter was over could he become a true new step.

Since becoming a cavalry captain, Hu Laosan has had a team of elite cavalry and a thousand-household battalion under his command. He also adopts a strategy of attacking and suppressing uprisings in various places.

To prove that he was not only good at charging into battle, Hu Laosan naturally wanted to do something, so he simply chose a target and prepared to take action.

Originally, Hu Laosan thought this matter wouldn't be too difficult for him, after all, it was just a rebel army, and he had seen their fighting power before. But this time he realized that he had really underestimated the situation.

Even though it was just a random selection, he ended up in the same team as that strategist, and was facing the army under that strategist's command. This made Hu Laosan quite uncomfortable.

After several clashes, Hu Laosan realized that while he was indeed quite capable in troop deployment, his ability to mobilize troops was severely lacking once a real battle broke out.

Although there weren't many people, it was impossible for them to rush forward all at once. The strategist always managed to plant some spies during Hu Laosan's pursuit to slow down Hu Laosan's speed and prevent him from catching up with his opponent.

Now, Hu Laosan has successfully cornered the strategist in a small town, but this small town has become an extremely difficult nut to crack.

After trying several times and realizing he had no way to take this place, Hu Laosan had no choice but to send a letter to Ning Ye asking for help. After all, it wasn't shameful to ask his family for help when he couldn't win.

Hu Laosan knew very well that this strategist was very important, and compared to his own reputation, capturing this strategist was more important.
